Import python module from parent subdirectory

Question

I tried different methods shown on multiple sites but couldnt figure out the problem. I need to import "demo1.py" in "demo2.py". Here is my folder hierarchy:

Project:___ __init__.py
         |_ main.py
         |_ Package1:___ __init__.py
         |            |_ demo1.py
         |_ Package2:___ __init__.py
                      |_ demo2.py

When I have this in main.py, it works.

import Package1.demo1
import Package2.demo2

But this doesnt work in demo2.py

import Package1.demo1

Neither does this:

import Project.Package1.demo1

I tried following this tutorial https://www.programiz.com/python-programming/package but Im doing something wrong. Tried renaming "main.py" to something else in case it is causing problems but that doesnt helped either.

Edit: Solution found

from sys import  path 
import os

par_dir = os.path.abspath(os.path.join(os.path.dirname( __file__ ), os.pardir))
path.append(par_dir)
import Package1.demo

from sys import path
path.append("project-path")

Define it inside of demo1 or demo2, it will work. You may check this question.
